T 0 all whom it may concern:

, Be it known that 1, San S. RUNDELL, a citizen of the United States,residing at Bogalusa, in the county of Washington and State ofLouisiana, have invented a new and useful Oil Cup, of which thefollowing is a specification.

This invention aims to provide novel means whereby heavy grease andliquid oil may be supplied to a part to be lubricated.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains.

Although a preferred embodiment of the invention has been shown, it willbe understood that a mechanic, working within the scope of what isclaimed, may make changes, without departing from the spirit of theinvention.

In the drawings :-Figure 1 shows in longitudinal section, a deviceconstructed in accordance with the invention; Figure 2 is a crosssection on the line 22 of Figure l; and Figure 3 is a fragmentalelevation showing a slight alteration, in the form depicted in Figure 1.

The device comprises a casing, denoted generally by the numeral 1, thecasing comprising a tubular body 2, secured in any desired way, as at 3,to the member 4 which is to be lubricated, the said member having anopening 5, through which both the heavy grease and the liquid lubricantare dis charged For the sake of strength, the body 2 has an enlargedupper end 6 into which is threaded closure '7 for the body 2, theclosure having an outstanding flange 8 engaging the part 6 oi? the body2. The closure 7 is provided with a chamber 9 for liquid oil. A tubularguide 10 is secured by threading or otherwise in the inner end of theclosure 7, the liquid oil fiinding its way from the chamber 9 into thetubular guide or discharge member 10, through a small passage 11fashioned in the closure 7 at the inner end of the chamber 9. Thecombined guide and discharge member 10 has a tapered lower end 12 whichextends into the opening 5 in the member 4:, without filling and closingthe said opening. If desired, and as shown in Figure 3, the guide tubeand discharge member may extend through the opening in the member to belubricated; and in Figure 3, parts hereinbefore described are designatedby numerals previously used, with the suflix a.

A plunger 14, in the form of a disk, fits closely but slidably in thetubular body 2 and is mounted slidably on the tubular discharge member10. The plunger 14: has a hub 15, about which is engaged one end of .ahelical compression spring 16, surroundingthe discharge member 10, theother end of the spring being received in a seat 17 formed in the member7. The spring is shown in Figure 1 as partly compressed, and as thespring expands, the downward or inward movement of the plunger 1% islimited by one or more stops 18 on the discharge member 10, theconstruction being such that when the device is assembled shown inFigure 1, but before the body 2 is connected to the member 1, the spring16 cannot force the plunger out of the tubular body 2, the device thusbeing held assembled, ready for mounting on the part 1 which is to belubricated.

The casing 1 includes an inlet member 19, threaded into the chamber 9 ofthe closure 7 and provided with an enlarged head 20 bearing upon theouter end of the closure 7. The inlet member 19 has a chamber 21communicating with the chamber 9 of the closure 7, there being an inletopening 22 in the member 19, and the member 19 being provided with avalve seat 23 located between the opening 22 and the chamber 21.

The opening 22 in the inlet member 19 is controlled by a valve 24,adapted to cooperate with the seat 23 and provided with a hub 25 fromwhich projects a cleaner 26, in the form of a rod, adapted toreciprocate in the tapered end 1.2 of the discharge mem ber 10, for thepurpose of removing 0bstructions. A compression spring 27 surrounds thehub 25 of the valve 24, one end of the spring engaging the valve, andthe other end of the spring engaging the closure 7 at the inner end ofthe chamber 9.

v In practical operation, the closure 7 and parts carried thereby areremoved from the body 2, and the body is filled with heavy grease. Theclosure 7 is replaced, the

plunger 14': resting on top of the grease, and

the spring 16 being compressed. The spring 16 expanding, will tend tomove the plunger 14 inwardly, and the plunger will force the heavygrease through the opening 5 in the member 4. The valve 24 may be forcedinwardly by the spout of an oil can, "and liquid oil may be shot intothe chanibers21 and 9, the liquid oil flowing through the passage 11,and through the -disch-arge member "'10, to the place "Where lubricationis required. The spring 27 tends to hold the valve 24- in closedposition, and each time that the valve 24 is moved, the rod 26 will bereciprocated, thereby cleaning out the reduced end 12 of the dischargemember a s 1 item I claim 7 v '1. In a device of the class described, acasing having an inner chamber for heavy grease, and an outer chamberfor light grease, a discharge member communicating With the outerchamber and extended throughthe inner chamber, a plunger "slid-"dlo'sure for the outer chamber, spring means for holding the valveseated, and a cleaner carried by the valve and operating in thedischarge member.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two Witnesses.
